一开始这个功能的实现，我使用了marquee，后来发现marquee已被废弃，没办法还是使用css+js来实现

// 工具方法
function hasClass(obj, cls) {
return obj.className.match(new RegExp('(\s|^)' + cls + '(\s|$)'));
}
function addClass(obj, cls) {
if (!this.hasClass(obj, cls)) obj.className += " " + cls;
}
function removeClass(obj, cls) {
if (hasClass(obj, cls)) {
var reg = new RegExp('(\s|^)' + cls + '(\s|$)');
obj.className = obj.className.replace(reg, ' ');
}

removeClass(obj, cls)
